In a photoelectric effect experiment, the stopping potential depends on which of the following factors?
- A.Intensity of incident light
- B.Frequency of incident light
- C.Distance of the source from the metal
- D.Time of exposure to light
Show correct answer & step-by-step solution
Correct answer: B — Frequency of incident light
Solution
- Einstein's photoelectric equation is .
- The stopping potential is related to maximum kinetic energy by .
- Thus, .
- The stopping potential depends only on the frequency and the work function .
- Hence the answer is (B).
